(Y/N/N) = Your nickname, (Y/N) = Your name

SPN episode 23 of season 13 rewrite with prompt below. Took me about 15 minutes to write, just wanted to get something out...feedback welcome, enjoy...

"And just like that, the person I'd been kissing moments ago became the most dangerous person in the world."

It felt like it had been hours, Sam had told Jack to kill him, Lucifer just stood there with a stupid smile plastered across his face, Jack had tried to stab himself…But just like always Dean had made the next move first, coming in with the blink of an eye, spreading angel wings across the door of the church. The rest happened in the flash of time, frozen at times, sweeping across a plan of existence that didn't seem fair. Dean and Lucifer battling things out, and a angelic duel, Dean finally getting the upper hand. The whole church…the whole world…held a collective breath, until finally Lucifer lay sprawled on the floor, dark wings burned into the floor around him, Sam collected Jack. Dean, after catching his breath come to collect me from my position weak and down for the count near a collapsed bench.

"Is it finally over?"

Jack asked taking stock of the situation.

"It's finally over. For real this time. You did it."

Sam said, letting out a breath that seemed to have been held for years. He looked over at Dean and I.

"No, we did it…(Y/N/N, are you okay?"

I smiled and hugged my arm closer to my side.

"I have been worse. Dean?… What?… How?…What is going on with you?"

I wrapped my hand around his arm, he looked me in the eyes for a brief moment, he looked different, sad, but at the same time radiating with power. He leaned down and gave me a kiss, quick and soft. He ran a hand down my face and I grabbed his wrist.

"Dean? Answer (Y/N)'s question…How did you do that? Where is Micheal and Castiel?"

Dean stepped away, back toward the door of the church, he looked tiered, but gave a smile.

"Cass is fine, I did what I had to do, we have some terms…"

Dean buckled over, as if he was in pain, I moved to reach for him, but was stopped by the arm of Sam, he gave me a look and I meet it back with a death glare, trying to will him into letting me pass. Dean yelled out in pain.

"NO! We had a deal! You promised!"

All of a sudden you could feel the change in the air, "Dean" straightened up, his evergreen eyes having turned a dark brown, his stance becoming slightly more straight. The feeling of power, raw, ancient and dark, filling the space in a breath of a second.

"Thank you."

And with that "Dean" flashed out with the sound of angel wings left ringing in my ears. I collapsed into Sam's arms. And just like that, the person I'd been kissing moments ago became the most dangerous person in the world.
